Hey Philipp,
personally i use 3dsmax and therefore the Babylon.js script/plugin to export all my animated meshes/models.
Everything works fine so far.
One of the things you really need to take care of is to limit "maximum vertext per bones to 4". This can be set in any other application as well and is a must. glTF can not handle more than 4 vertices per bone. Usally it will spit out an error message and or not export the model at all.
None of the 3D tools i know have an implemented glTF exporter, therefore there may be some issues here and there... 3dsmax did work best for me personally... next to blender...
It would be interesting to know which models did throw an error, especially the ones from Khronos! All version 2 should work if got the developer right.
our actual supported format is glTF model 2.
regards
Dennis
